Rigless Operations and Reduced Emissions: Advancing ESP Performance with Microemulsion Technology

Abstract This paper investigates the application of microemulsion technology to dissolve scale deposits, extend the operational lifespan of Electrical Submersible Pumps (ESPs), enhance well productivity, and reduce workover (WO) costs. It aims to demonstrate the dual benefits of economic efficiency and environmental sustainability in oilfield operations. The study integrates field data and case studies from Badr El Din Petroleum Company (BAPETCO) in the Western Desert of Egypt. The methodology includes the application of microemulsion treatments in routine maintenance protocols for ESPs. Detailed procedures involve pre-treatment diagnostics, and the systematic implementation of treatments, followed by monitoring and analysis of ESP performance metrics. The implementation of microemulsion treatments at BAPETCO's operations has yielded significant improvements. Results indicate a 60% increase in the mean time between failures (MTBF) of ESPs, rising from an average of 16 months to over 24 months. Overall well productivity increased by 67%, with average production rates improving from 290 barrels per day (bpd) to 490 bpd. Field data show a marked reduction in scale-related failures and associated WO interventions, decreasing by 30%. Additionally, the adoption of this technology has led to a reduction in CO2 emissions by 15%, and minimized environmental footprints due to fewer workovers and reduced logistics. These outcomes underscore the effectiveness of microemulsions in improving both the operational efficiency and environmental sustainability of oilfield operations. This paper provides novel insights into the practical application of microemulsion technology in real-world oilfield operations, specifically within the context of the Western Desert of Egypt. The findings contribute to the existing body of knowledge by demonstrating the economic and environmental benefits of this innovative treatment, offering a viable solution for other operators facing similar challenges.
